Interactive 3D visualisation technique used in pulmonary rehabilitation in chronic obstructive pulmonary disease: A randomised controlled study evaluating quality of life, compliance and use of health care.

Introduction: A pulmonary rehabilitation (PR) programme, including exercise training, education, and behaviour change, is highly recommended in treatment guidelines for chronic obstructive pulmonary disease (COPD). A new PR educational material for PR using an interactive three-dimensional (3D) visualisation technique was developed. There is little known regarding using 3D in this setting. The aim was to evaluate, within a PR programme setting, differences between outcomes of education through interactive 3D compared with education by means of 2D visualisation in patients with COPD regarding health-related quality of life (HRQL), physical capacity, exercise self-efficacy, compliance to exercise training, compliance to medication, and the use of health care and to describe learning styles. Methods: Patients were cluster randomised to PR at the University Hospital clinic, including exercise training, for 10 weeks with education by 3D ( Results: No significant differences were observed in HRQL in relation to COPD between the groups after 10 weeks. Differences were found in handgrip strength at baseline and at 10 weeks ( Conclusion: An interactive education in 3D technique used in a PR programme for patients with COPD yielded no significant differences compared to conventional techniques. Three-dimensional techniques can be used in PR for COPD as an alternative to conventional techniques. ClinicalTrials.gov (identifier:NCT02802618).
